shutdown — shut down socket send and receive operations

---

Синопсис (Synopsis)

#include <sys/socket.h>

       int shutdown(int socket, int how);

---

Описание (Description)

The shutdown() function shall cause all or part of a full-duplex
       connection on the socket associated with the file descriptor
       socket to be shut down.

       The shutdown() function takes the following arguments:

       socket      Specifies the file descriptor of the socket.

       how         Specifies the type of shutdown. The values are as
                   follows:

                   SHUT_RD     Disables further receive operations.

                   SHUT_WR     Disables further send operations.

                   SHUT_RDWR   Disables further send and receive
                               operations.

       The shutdown() function disables subsequent send and/or receive
       operations on a socket, depending on the value of the how
       argument.

Возвращаемое значение (Return value)

Upon successful completion, shutdown() shall return 0; otherwise,
       -1 shall be returned and errno set to indicate the error.

---

Ошибки (Error)

The shutdown() function shall fail if:

       EBADF  The socket argument is not a valid file descriptor.

       EINVAL The how argument is invalid.

       ENOTCONN
              The socket is not connected.

       ENOTSOCK
              The socket argument does not refer to a socket.

       The shutdown() function may fail if:

       ENOBUFS
              Insufficient resources were available in the system to
              perform the operation.
